hi Narayana,

thanks for posting this, so 100% sure a vpn errors can be super frustrating )) so, first off, error 53003 usually means the vpn client can't talk properly to azure ad for authentication. since ur device shows as 'compliant', that's a good sign, but something's still blocking the handshake.

go to the azure portal and check the conditional access policies. sometimes they get too strict and block valid connections. make sure 'azure vpn' is listed as a trusted app in the conditional access rules.

also, try re registering the device in azure ad. just open command prompt as admin and run dsregcmd /leave then reboot and reconnect. this often clears up weird auth states.

check if the device cert is valid and hasn't expired. if ur org uses scep or pkcs, maybe the cert didn't deploy right.

aha, and dont forget the classic 'turn it off and on again' move. restart the vpn client, restart ur machine, maybe even bounce the vpn gateway if u have access.

worth looking into the network stack too. if ur behind a corporate proxy or firewall, it might be snipping the vpn packets. try from a different network if u can.

let us know if any of this clicks,

rgds,
Alex
